" The object of the invention is to provide a simply constructed mold,of this chara'c'er 25* member is employed for each row-of blocks whichmay be quickly assembled and taken apart and the size of whieh may beextend ed indefinitely by, adding more mold inennv hers to provide forthe 'moldingof 1 number of blocks simultaneous Another object is toprovid molding sii'miltaneously a multipllcr ticles such as blocks orthelike' which so constructed that only one longitudinal -ms.

The end plates which are exactly alike are preferably constructed in thefornr shown in Fig.1 with lateralflanges 10 and 11 projecting outwardlyfrom its upper and lower edges to reinforce and stiffen said pla-tes.Each plate 3 has a plurality of transversely extending longitudinally. Tspaced slots 12 positioned to receive the apertured lugs 2 which projectfrom the ends'of the strips 1, the openings in said lugs being sopositioned that when a pin 13 is driven into said openings, the backplate will wedge uptight against it asis shown clearly in Fig. 4. Theseend plates. 3 are also preferably provided with transverselyextendingbracing ribs 14 arranged at suitable intervals and secured theretobetween the flanges 10 and 11 thereof as is shown clearly in Fig- 1,saidt-lreinforcing ribs. being here shown in the form of metal platesfolded upon themselves interniediately of their ends and havinglaterally extending feet 15 which are riveted or otherwise secured tothe plate-3. The ends of these plates 3 are provided with apertured lugs01' ears .16

arranged at their upper and lower'edges which are designed to overlapwhen two 45' plates are employed and by means of which the plates aresecured together bypassing a fastening pin 17 through said'aperturedears. 7 V

In the form sliojv-i igiii'Fig. 5 when it is desired to produce blockshaving registering posite faces, th

longitudinal grooves or recesses in their opmember 1' is employed whichis provide on its opposite faces with longitudinally extending outwardlybulged members 19 so that when this form of mem- I "her, is employedboth faces or side edges lfof the block will be, grooved so that wh nthe blocks are assembled there a 1ongitudinally extending air spacebetween them such as is often employed in connection with buildingblocks.

When setting up a mold for making a large number of blocks orotherarticles, the

longitudinal members. 1 are arranged on a hard floor in parallelrelation and after the spacing or division plates 4 have been positionedin respect to the various members, the end plates 3 are applied byengaging the tongues or lugs 2 with the slots 12 in said end plates andby driving in the wedge pins 13 whereby said longitudinal members anddivision plates are securely locked in operative position ready toreceive the'cement for forming the molded articles, then the concrete ispoured into the molds byany suitable means not shown and is. leveled offinthe usual manner. The blocks are then allowed to set for twenty-fouror thirty hours when they will be found to be sufiiciently strong to beremoved and stacked up tocoinplete the setting process. It -is of courseunderstood that to remove the-molded articles, the assembling process isreversed,

members detached, then one of'the longitudinal members is removed andthe blocks confined thereby may be taken away and carried to asuitableplace of deposit and. I

the nextlongitudinal member is removed and the process cont nued'untilall '.of the blocks have been'removed and stacked.

Vhile Iv have described this improved I mold in connection with theformation of blocks, it is to be understood that it may be used forproducing any sort. of moldedce-a ment articles.j.a'll that is necessarybeing to have the molds of the required shapes,- the articles beingemployed.
